Description

[Detailed Description of the Invention] The present invention relates to a scale plate mounting mechanism that requires a small number of parts.

The frequency scale plate of a radio receiver is fixed, for example, as shown in FIG. In the figure, 1 is a scale plate, and on its surface, AM/FM information is displayed, 53...
It is printed with characters for frequency display and stereo (ST) display, such as 160, and is illuminated by various lamps. 2 is a holder equipped with two lamps that irradiate the AM/FM part, 3 is a holder equipped with two lamps that irradiates the ST, and 4 is a lamp that irradiates the frequency part (fixed to a printed circuit board not shown). It is. Reference numeral 5 designates a back plate that welds and holds the scale plate 1 on the front side, and lamp holders 2 and 3 are mounted on the back side of the back plate.
Frames 6 and 7 are provided into which are inserted.

The lamp holders 2 and 3 are made of black rubber and have two chambers each separately accommodating two lamps. The back plate 5 is made of an opaque material and has through holes (indicated by broken lines) formed therein corresponding to each lamp. In this mounting mechanism, the scale plate 1 is welded to the back plate 5, and then the plate 5 is further screwed to another member, such as the mounting part of a push button tuner (not shown), using screws 8. It is complicated, has many parts, and has the drawbacks of requiring a lot of man-hours for installation.

The present invention utilizes the elasticity of a rubber lamp holder to attach the scale plate to the main body of the device at the same time as the lamp holder using a small number of parts.

The present invention is a mechanism for attaching a scale plate such as a frequency display to the main body of the device, and a shielding frame is provided on the front part of the device body to block external light from the surroundings, and from around the frame to the inside of the device. A plurality of protrusions are made to protrude from the lamp holder, and holes corresponding to the protrusions are formed in each of the rubber lamp holders that illuminate both ends of the scale plate, and the protrusions are press-fitted into the holes of the lamp holder. When the holder is attached to the rear of the shielding frame, the scale plate is interposed between the two to close the rear opening of the shielding frame. This will be explained in detail with reference to an example.

FIG. 2 is an assembled perspective view showing an embodiment of the present invention, and numeral 11 is a front plate of the main body of the device. A long hole 12 for arranging a plurality of push buttons is formed below the front decorative plate 11, and a rear shielding frame 13 is formed above the long hole 12 using a side wall. In this example, the scale plate 1 is attached so as to close the rear opening of the closing frame 13. That is, four lamp holder fixing protrusions 14 are provided around (outside) the shielding frame 13, and on the other hand, the rubber lamp holders 2, 3
have two holes 1 each corresponding to these protrusions 14.
5, the lamp holders 2 and 3 are connected to the hole 1.
The protruding portion 14 is press-fitted into the portion 5 . At this time, the lamp holders 2 and 3 and the shielding frame 13
By interposing the scale plate 1 between them, the scale plate 1 can also be attached at the same time.

Since the protrusion 14 is provided outside the shielding frame 13 and the scale plate 1 is formed with a recess 16 corresponding to the protrusion 14, there is an advantage that no light leaks through the gap after installation. FIG. 3 is an enlarged sectional view of this part. Of course, this recess 16 prevents the scale plate 1 from shifting laterally. Attachment of the rubber lamp holders 2 and 3 is effective by making the distance between the holes 15 and 15 slightly shorter than the distance between the protrusions 14 and 14, thereby increasing elasticity. The coefficient of friction also increases the holding force.

As mentioned above, according to the present invention, there is no need for a back plate as a separate member, and no screw fixing is required, so the number of parts is small, and the scale plate can be attached at the same time as the lamp holder, making the installation work extremely easy. It is easy (less man-hours).
